Answer:
x = 75 m
Step-by-step explanation:
This is a problem of similar triangles solved using proportions.
In similar triangles, corresponding side lengths are proportional.
Here the small and large triangles are similar because the have all three angles congruent.
By proportions, identifying corresponding sides,
x/45 = 50/30
solve for x
x = 45*(50/30) = 75 m
Answer:
3.5
Step-by-step explanation:
[(3 x 2) - 2 x 1.25] = [6 - 2 x 1.25]
= [6 - 2.5]
= 3.5
It's the last one. 0.2 could be changed to 2. That would give you what 40% of 70 is.
To find the perimeter<span> of a polygon, take the sum of the length of each side. The formula for </span>perimeter<span> of a triangle would be the sum of the three side lengths (a +b+c). In the case, where it is a regular polygon, the perimeter would be 3 times the side length. Hope this answers the question.</span>
